How can you catch your cheating boyfriend? For some people, this is a very easy thing to do. But, others might find it hard, especially if they don't want to invade their romantic partner's privacy.

This is not the case for 'Call Her Daddy' podcast host Alexandra Cooper as she shared the genius investigation that allowed her to reveal her boyfriend's cheating. She explained how she uncovered her boyfriend's deception when she was in college at Boston University. Here's how the American podcaster did it.

How 'Call Her Daddy' Podcast Host Catches Her Cheating Boyfriend

Alexandra Cooper said that it all started when her college boyfriend left his phone with her, unattended.

"A man's phone, unattended. Me, by myself with a man's phone," she said via Fox News.

"I couldn't walk away from this opportunity. And I don't know what woman could. Maybe if you're in a healthy relationship, but I wasn't," explained the "Call Her Daddy" podcaster.

Since her boyfriend's phone was with her, she decided to guess his password. In her first attempt, she tried using the man's Netfix password, which worked immediately. This is when she discovered that her partner was texting multiple girls during their relationship. She decided to focus on the most recent texts.

Unfortunately, the name of the girl wasn't saved on the guy's phone. Aside from this, he didn't mention his other lover's name. Although this is the case, Alexandra Cooper was sure that her boyfriend was cheating. She saw that her partner asked the unknown person to enter his bedroom. Cooper said that it was obvious they weren't meeting for a prayer group.

Since she couldn't confront her boyfriend without knowing the girl's name, she decided to call the number under *67. This made her call populate as "restricted," allowing her to receive a voicemail, which revealed the woman's first name; Kaylee.

After that, she checked all the photos they sent to each other and discovered that the woman was a bartender. Alex searched all the Port St. Lucie bars near their area and narrowed it down to seven contenders. She called each bar to ask for a girl bartender named Kaylee. One of the bars confirmed that they had an employee named Kaylee, which proved her speculation.

When she got all the needed information, such as the girl's name and the bar she worked at, she confronted her boyfriend. She pretended that one of her Boston University friends told her about the other lover, claiming that Kaylee bragged about how she and the man cheated on her.

Being cornered, her ex-boyfriend finally admitted that he was having a sexual relationship with Kaylee. He tried apologizing to Alexandra Cooper, but she had enough. The American podcaster said that this was one of the finest and most genius moments in her life.
